The Korean Fair Trade Commission raided the studio's Seoul office to gather evidence as to whether or not Blizzard violated the country's law. There had been complaints in Korea that Blizzard was refusing to refund players who purchased and were attempting to return Diablo III.

Miffed punters who couldn't log into the game were denied a full refund by Blizzard, which said that it was under no obligation to do so under the game's contract. The studio claims that it has a strict policy of "no refunds" in the country if a product is used.

Players complained to the FTC and the commission responded by launching an investigation. The investigation will sort through the seized documents and evidence to see if there is a possible violation of Korea's electronic commerce and commercial contracts law.

Apparenlyt Diablo III players are not to be messed with and the FTC had loads of complaints. Blizzard has since vowed to increase server capacity, to improve the game for players but it is not going to give anyone's money back.
